Description

Vorrichtung zur stufenlosen Veränderung der Umlaufzahl der Werkzeuge von Rühr-und Schlagmaschinen Die Erfindung betrifft eine Vorrichtung zur stufenlosen Verstellung der Umlaufzahl der Werkzeuge von Rühr- und Schlagmaschinen während des Betriebs. Bei diesen Maschinen erweist es sich häufig als notwendig, die Drehzahl des Werkzeugs der wechselnden Konsistenz des zu bearbeitenden Gutes, also beispielsweise eines Kuchenteiges, anzupassen, was meist erst während der Arbeit festgestellt werden kann.Device for the infinitely variable change of the number of revolutions of the tools of stirring and beating machines The invention relates to a device for stepless Adjustment of the number of revolutions of the tools of stirring and beating machines during the Operating. With these machines it often turns out to be necessary to adjust the speed the tool of the changing consistency of the material to be processed, for example a cake batter to adapt, which is usually only noticed during work can.

Gegenstand der Erfindung ist eine diesem Zwecke dienende Vorrichtung, die mit einfachen Mitteln und geringem Platz- und Gewichtsbedarf eine entsprechende Umstellung auf eine gewünschte Umlaufzahl ermöglicht, ohne daß die Maschine zu diesem Zweck stillgesetzt werden muß.The subject of the invention is a device serving this purpose, which is a corresponding one with simple means and little space and weight requirements Allows conversion to a desired number of revolutions without the machine having to do this Purpose must be stopped.

Die Vorrichtung besteht aus zwei an sich bekannten, axial gegeneinander verstellbaren Tellerscheiben mit einander zugekehrten kegelförmigen Flächen, zwischen welchen der Antriebsriemen des Werkzeugs so verschoben werden kann, daß sich das Übersetzungsverhältnis zwischen der Antriebswelle und der auf der Werkzeugspindel sitzenden Riemenscheibe im einen oder anderen Sinne ändert, wobei erfindungsgemäß eine Tellerscheibe fest, die andere Tellerscheibe über einem Schneckengetriebe durch Steigflächen aufweisende Scheiben verstellbar ist. Der Winkel der Steigflächen der Scheiben entspricht hierbei dem Winkel der Kegelflächen der beiden Tellerscheiben, der wiederum mit dem Winkel der Seitenkanten des keilförmigen Riemens übereinstimmt.The device consists of two known per se, axially against each other adjustable plate washers with conical surfaces facing each other, between which the drive belt of the tool can be moved so that the Gear ratio between the drive shaft and that on the tool spindle seated pulley changes in one sense or another, wherein according to the invention one cup washer, the other cup washer through a worm gear Slices having rising surfaces is adjustable. The angle of the risers of the The washers corresponds to the angle of the conical surfaces of the two cup washers, which in turn corresponds to the angle of the side edges of the wedge-shaped belt.

Vorzugsweise ist die Anordnung so getroffen, daß mit dem Schneckenrad eine Scheibe fest verbunden ist, gegen welche sich die bewegliche Tellerscheibe über ein Kugellager abstützt. Beide Tellerscheiben sitzen mit Kerbverzahnung auf einer durchgehenden Nabe, die ihrerseits unmittelbar von der Motorwelle aus angetrieben werden kann, wobei die eine Tellerscheibe axial unverschieblich, die andere längs der Kerbverzahnung verschiebbar ist.The arrangement is preferably such that with the worm wheel a disc is firmly connected against which the movable plate washer supported by a ball bearing. Both plate washers sit on with serrations a continuous hub, which in turn is driven directly from the motor shaft can be, with one cup washer axially immovable, the other lengthways the serration can be moved.

Ein Ausführungsbeispiel einer Drehzahlverstellvorrichtung für eine Rühr- oder Schlagmaschine gemäß der Erfindung ist in der Zeichnung in schematischer Form in einem axialen Schnitt dargestellt. Die Zeichnung zeigt in ausgezogenen Linien die Stellung der Getriebeteile bei kleinstem Durchmesser der Antriebsseite; mit strichpunktierten Linien ist die äußerste Stellung des Riemens angedeutet.An embodiment of a speed adjustment device for a Mixing or beating machine according to the invention is in the drawing in schematic Shape shown in an axial section. The drawing shows in solid lines the position of the gear parts with the smallest diameter of the drive side; with The outermost position of the belt is indicated by dash-dotted lines.

Mit 1 ist das fest mit dem nicht dargestellten Maschinengestell verbundene Gehäuse des Antriebselektromotors bezeichnet, mit 2 die Motorwelle, mit der die Nabe 3 fest verbunden ist. Auf der Nabe 3 sitzen mit Kerbverzahnung die Tellerscheiben 4 und 5, zwischen deren einander zugekehrten Kegelflächen der Keilriemen 6 mit Reibungsschluß geführt ist.With 1 is firmly connected to the machine frame, not shown Housing of the drive electric motor designated, with 2 the motor shaft with which the Hub 3 is firmly connected. The cup washers sit on the hub 3 with serrations 4 and 5, between their conical surfaces facing each other, the V-belt 6 with frictional engagement is led.

Die Tellerscheibe 5 ist mit der Nabe 3 fest verbunden. Die Tellerscheibe 4 sitzt dagegen längs der Kerbverzahnung axial verschiebbar auf der Nabe und ist über ein Kugellager 7 gegen eine Druckscheibe 8 abgestützt, die in ein Schneckenrad 9 eingepreßt und mit diesem axial beweglich ist. Die Scheibe 8 weist unten eine oder mehrere Steigflächen auf, mit welchen sie auf entsprechenden Steigflächen einer fest mit dem Gehäuse verbundenen Scheibe 10 aufliegt, derart, daß sie bei einer Verdrehung längs dieser Steigflächen gehoben oder gesenkt wird.The cup washer 5 is firmly connected to the hub 3. The plate washer 4, however, sits axially displaceably on the hub along the serration and is supported by a ball bearing 7 against a thrust washer 8, which is in a worm wheel 9 is pressed in and axially movable with this. The disc 8 has a bottom or several rising surfaces, with which they are on corresponding rising surfaces one rests firmly connected to the housing disc 10, such that it is at a Rotation is raised or lowered along these riser surfaces.

In die Verzahnung des Schneckenrades 9 greift eine Schnecke 11 ein, die mit ihrer Welle 12 in mit dem Maschinengestell fest verbundenen Lagern 13 gelagert ist. Die Schnecke kann mit Hilfe eines nicht dargestellten Handrades während des Betriebs in Richtung des Pfeiles A verdreht werden. Dabei werden infolge Verdrehung des Schneckenrades 9 die Teile 9, 8, 7 und 4 in Richtung der Pfeile B gegen den Riemen 6 und letzterer gegen die feststehende Tellerscheibe 5 gedrückt.In the toothing of the worm wheel 9, a worm 11 engages, which is mounted with its shaft 12 in bearings 13 firmly connected to the machine frame. The worm can be turned in the direction of arrow A during operation with the aid of a handwheel (not shown). As a result of the rotation of the worm wheel 9, the parts 9, 8, 7 and 4 are pressed in the direction of the arrows B against the belt 6 and the latter against the stationary plate washer 5.

Der Riemen 6 weist an seinen Laufflächen die gleichen Schrägen auf wie die beiden Tellerscheiben und wandert bei Bewegung der Schnecke 12 nach außen oder innen, also vom kleinsten zum größten Durchmesser der Tellerscheibe, oder umgekehrt. Dadurch kann das Übersetzungsverhältnis zum angetriebenen Teil nach Bedarf verändert werden. Die Drehzahlverstellung kann hierbei nur erfolgen, solange,die Tpllersc heben im Umlauf sind.The belt 6 has the same bevels on its running surfaces like the two plate washers and migrates outward when the worm 12 moves or inside, i.e. from the smallest to the largest diameter of the plate washer, or vice versa. This allows the transmission ratio to the driven part to be changed as required will. the The speed can only be adjusted as long as the Tpllersc lift are in circulation.
